If you are a DIY addict and intend to build a stone fire pit on your own, you simply can’t do without a fire pit liner. These liners are usually made of stainless steel (though other metal options are possible too) and feature a strong resistance towards high temperature. The dimensions of liners greatly differ. Therefore, depending on the size of the pergola you plan constructing, you can always find a matching fire pit liner!
